NORMAN G. TURNER 0 By @mui United States Patent U.S. Cl. 52-100 4 ClaimsABSTRACT OF THE DISCLOSURE A reglet section for use with a concretewindow sash form, the reglet channel being closed by a removable tearstrip and the channel rim being formed with lateral rim anges havinganchor ribs thereon which prevent pulling of the reglet section into thewindow sash opening when the form is stripped from the concrete. In aspecial form of the reglet construction a series of saw cuts or slotswhich extend partially through the reglet section, enable the latter tobe bent to curved shape to accom-1 modate a window sash opening having arounded corner. A roughened channel interior serves to lock a glazinggasket in position within the channel of the reglet section.

The present invention relates generally to concrete buildingconstruction and has particular reference to channel-forming deviceswhich are commonly known as reglets. Still more specifically, theinvention is concerned with reglets which are employed in connectionwith rectangular concrete forms whereby rectangular gasket-receivingchannels are formed around window openings and are adapted to formwindow sashes for glass panes.

It is common practice, in connection with the use of reglets of theparticular type under consideration to provide a rectangular woodenform-forming frame which is adapted to have concrete poured therearound,and temporarily defines the four sides of the window opening to beformed in the concrete structure, and to secure four of the reglets tothe outer side surfaces of the frame in such a manner that their channelopenings are closed off by the frame boards, that is, face inwards inthe direction of the window opening. In order to exclude concrete fromentering the interiors or channels of the reglets, the reglets usuallyare provided with laterally extending flat rim anges through which nailsare driven into the frame boards. It has been found, however, thatregardless of the number of nails which are employed or of the tightnesswith which the nails are driven into the boards of the rectangularform-forming frame, concrete seepage into the channels is not usuallycompletely prevented. Furthermore, where a large number of closelyspaced nails are employed, difficulty is encountered in stripping theform-forming frame from the hardened concrete and alSo there is atendency for the reglets to be pulled inwardly of the window opening andaway from the portions of the concrete around such opening.

The present invention is designed to overcome the above-notedlimitations that are attendant upon the use of flat lateral rim flangeson Window sash reglets, and tow-ard this end, the invention contemplatesthe provision of a novel reglet or reglet section which, althoughemploying laterally extending rim flanges, makes provision whereby theouter edge regions of such flanges make interlocking engagement with theadjacent poured concrete so that when the contiguous form board isstripped from the hardened concrete, the rim flanges as well as thereglet as a whole will not tear or pull loose from the concrete.According to the present invention, the rim flanges of the improvedreglet are not nailed to the adjacent form board, other securing meansfor the reglet being provided. Neither are the rim flanges employed forthe prevention of concrete seepage into the reglet interior or channelsince other seepage prevention means is employed. The sole function ofthese rim flanges is, therefore, to enhance the bond between the regletand the surrounding concrete so that stripping of the adjacent formboard from the concrete will not disturb the position of the reglet.

In order positively to prevent concrete seepage into the reglet channel,a tear flap extends across the month of the channel and lies in thecommon plane of the rim fianges. Any concrete which may flow past therim flanges is prevented from entering the channel of the reglet byreason of this tear flap. After the adjacent wooden form board has beenstripped from the hardened concrete, the tear ap may readily be pulledor ripped progressively from across the mouth of the reglet channel,thus exposing the channel for gasket-receiving purposes.

Initial securing of the reglet to the adjacent form board is effected bydriving a series of nails through the channel web and also through thetear flap. After said adjacent form board has `been stripped from thehardened concrete, the projecting ends of the nails may be cut fiushwith the tear strip to enhance removal of the latter from the channelmouth.

Heretofore, with reglets of the type under consideration, consider-abledifficulty has been encountered in attaining accurately fitting matingreglet ends which, when brought together, are intended to produce squarecorners. The present invention obviates this difficulty by providing aprefabricated corner reglet which is accurately assembled at the factoryand supplied for use in the field so that fitting operations on anygiven 4board type rectangular concrete or frame are obviated.

Another feature of the present invention resides in the provision of amodied form of reglet which, although it preserves the aforementionedphysical attributes of the heretofore described reglet from thestandpoint of ready attachment to a wooden concrete form, prevention ofpulling away from the hardened concrete, etc., is of a flexible natureso that it may be bent to arcuate form to accommodate a window openinghaving a rounded corner, regardless of whether the corner be on a largeor a small radius. Furthermore, the modified form or reglet is capableof use in connection with a Window opening having an irregular orspecial shape, as, for example, a circular or oval window opening or anopening with a Gothic or other type of curved component.

Finally, the present invention embodies the use of novel splineconnector devices for adjacent reglet sections, such devicesaccommodating end-to-end fitting of reglet sections either in aligned orright angular relationship.

The provision of a reglet construction such as has briefly been outlinedabove constitutes the principal object of the present invention. Otherobjects and advantages of the invention not at this time enumerated willreadily suggest themselves as the nature of the invention is betterunderstood fro-m a consideration olf the following detailed descriptionor specification.

The invention consists in the several novel features which arehereinafter set forth and are more particularly defined by claims at theconclusion hereof.

In the accompanying two sheets of drawings forming a part of thisspecification, several illustrative embodiments of the invention areshown, together with the manner in rwhich these embodiments may beassembled on a form-forming iframe in order to produce a concrete windowsash.

FIG. 12 is a fragmentary side elevational view showing the regletsection of FIG. 11 bent to curved configuration and operatively appliedto a concrete window sash form.

yReferring now to the drawings wherein several forms of reglet sectionsembodying the present invention are illustrated, all of the illustratedreglet sections are preferably formed of a high-impact plastic materialsuch, for example, as polyvinyl chloride, the sections being preferablymade by an extrusion process. In FIG. 2, a complete reglet assembly foruse as part of a concrete window sash is shown as being nailed inposition on a rectangular formforming frame in a manner that will bedescribed presently, the assembly representing a preferred form of theinvention and including eight reglet sections, namely, four straightmedial sections 10 and four corner sections 12.

Both the straight medial sections 10 and the corner sections 12 embody apreferred form of the invention, one of the medial sections being shownin detail in FIG. 1 and one of the corner sections being shown in detailin FIGS. 9 and 10. The straight reglet section 10 of FIG. 1 involves inits general organization a main channel portion in the form of a pair ofopposed and spaced apart side walls 14 and a connecting web 116. Themouth of the channel portion is provided with an integral closure in theform of a tear strip 18 which is produced by the same extrusion typemanufacturing process as that of the reglet section itself and whichprevents seepage of the concrete into the interior of said 'channelportion during formation of the Window-equipped concrete slab with whichthe reglet is to be associated. In order to facilitate removal of thetear strip after the concrete slab has been formed, V-shaped grooves 20are provided along the longitudinal edges of the strip and at itsjuncture lines with the adjacent fill edge portions of the side walls14. The tear strip 18 may thus readily be pulled from theconcrete-embedded channel portion of the reglet section 10, and when itis so pulled, any concrete which may have adhered to the strip isremoved at the same time and a clean channel interior is presented forsubsequent insertion of a suitable glazing gasket in the ordinary orconventional manner of window erection.

The outer or free longitudinal edge portions of the side walls 14 areturned laterally outwardly in opposite directions to provide a pair ofcoplanar rim flanges 22 and the outer longitudinal marginal or edgeportions of these rim flanges are turned rearwardly in reentrant fashionwith respect to the side walls 14 and are shaped to provide a pair ofangularly disposed anchoring ribs 24 of wedgeshaped configuration incross section. Additionally, narrow coplanar anchoring flanges 26project laterally in opposite directions from the side edge portions ofthe web 16 of the straight medial reglet section 10 and lie in the planeof the web. The anchoring ribs 24 and the anchoring anges 26 are adaptedfor embedment in the poured concrete of the aforementionedwindow-equipped slab in a manner and for a purpose that will becomeclear presently.

As best illustrated in FIGS. 9 and 10 of the drawings, each cornerreglet section 12 is comprised of two substantially identical lengths12a and 12b of straight reglet sections having abutting end edges whichare cut on a 45 bias (mitered) and joined together in any suitablemanner, as for example, by heat-sealing or by the use of a suitableadhesive. The joint between the two sections is indicated by thereference numeral 30 in FIGS. 9 and 10. The cross-sectionalconfiguration of the lengths 12a and 12b is identical with that of thestraight medial reglet section 10 of FIG. 1 and, therefore, to avoidrepetition of description, identical reference numerals have beenapplied to the corresponding parts.

Referring now to FIG. 2 of the drawings, a concrete window sash form 32is shown as being positioned on a portion of a main concrete slab form33. The form 32 is of rectangular open frame-like construction andcomprises four wooden frame boards 34, 36, 38 and 40 ywhich areappropriately secured together by nails or other suitable fasteningdevices. 'Ihe boards 38 and 40 define the opposite jarmbs of the formWhile the boards 34 and 36 define the upper header and the lower sill,respectively. The aforementioned reglet assembly including the fourstraight medial reglet sections 10 and the four corner reglet sections12 is mounted on and around the outer sides of the form 32 so ascompletely to encompass the latter in the manner shown in FIG. 2. Toeffect the attachment of the reglet sections to the form 32, the varioussections are positioned with their channel mouths facing towards theform and with the rim anges 22 lying against and flush with the outerside surfaces of the form boards 34, 36, 38 and 40. Nails 42 are thendriven through the Webs 16 of the various reglet sections so that theytraverse the channels of the section and also pass completely throughthe tear strip and into the rectangularly arranged boards of the form 32as clearly shown in FIG. 3.

After proper mounting of the reglet assembly on the form 32 in themanner described above, concrete is poured between the four sides (notshown) of the main slabforming form 33 so that it surrounds the -windowsash form 32 and causes the reglet assembly to be embedded in theconcrete. After the concrete has beome hardened, the form 32 is strippedfrom the main form 33 and the walls of the window opening vare thusexposed.

As clearly shown in FIG. 6, the opposed or inner surfaces of the sidewalls 14 of the various reglet sections 10 and 12 are provided with alarge multiplicity of parallel, closely spaced, sharply definedretention ribs 41 which offer a high degree of frictional resistance tothe stem portion 43 of a conventional glazing gasket 44 such as is shownin broken lines in FIG. 6. Various forms of glazing gaskets are suppliedby different manufacturers, but essentially they are similar. Usuallysuch gaskets are formed of neoprene and they afford a channel or groove46 for reception of a glass pane 48.

Prior to insertion of the neoprene glazing gasket 44 into the channelsof the reglet sections 10 or 12, and immediately after the form 32 hasbeen stripped from the concrete, the tear strips 18 are progressivelypulled from the channel mouths of their respective reglet sections inthe manner shown in FIG. so as to expose the channel interiors. Theportions of the nail shanks which project through the channel interiorsare either cut off at their base regions, utilizing a suitable nippingtool, or they may be bent fiat against the webs 16 of the channelportions of the reglet section `by utilizing a suitable impact toolsuch, for example, as a hammer.

It will be appreciated that after the concrete has been poured aroundthe form 32 as previously described, the rim anges 22 which lie fiushwith the outer surfaces of the form boards 34, 36, 38 and 40 serve toprevent passage of the wet concrete behind the reglet sections. However,in the event of any slight seepage of concrete between the regletsections and the form boards, such concrete will be automaticallyremoved at the time the tear strips 18 are pulled from their associatedreglet sections or 12. During stripping of the form boards from thehardened concrete slab, the wedge-shaped anchoring ribs 24 will preventpulling of the rim flanges 22 away from the surfaces that define thewindow sash or opening position of the concrete. The anchoring ribs 26similarly will hold the channel portions of the reglet sections withinthe concrete against dislodgment.

In FIGS. 7 and 8, a modified form of straight reglet section 110embodying the present invention is shown. In this form of the invention,the cross-sectional shape of the reglet section remains identical withthe cross-sectional shape of the straight reglet section 10 of FIG. 1except for the fact that the laterally extending rim flanges 22 havebeen omitted. Therefore, in order to avoid needless repetition ofdescription, similar reference numerals but of a higher order have 4beenapplied to the corresponding parts as bet-Ween the disclosures of FIGS.7 and l, and of FIGS. 8 and 6. It will -be understood that the form ofreglet section of FIGS. 7 and 8 is readily adaptable to prefabricationof reglet corner sections similar in outline and function to thepreviously described corner sections 12.

Whether a given reglet assembly be concerned with reglet sections of thetype shown in FIG. 1 or in FIG. 6, accurate alignment of adjacent regletsections on the various form boards of the window sash form 32 iseffected by means of rectangular hexahedral connector spline blocks 50(see FIGS. 9 and 10). Such blocks may be made of the same polyvinylchloride material as that of the reglet sections themselves. The splineblocks are inserted in telescopic fashion into the adjacent ends of thereglet sections to be joined together and then the sections are pushedtoward each other in end-to-end contiguity.

In FIGS. 1l and l2, a further form of reglet section 210 is illustrated,this particular reglet section serving to accommodate the constructionof window sash opening that has a rounded corner region. Due to thesimilarity between the reglet section 210 and the reglet section 110 ofFIG. 7, and again in order to avoid repetition of description, similarreference numerals but of a still higher order have been applied to thecorresponding parts as between lthe disclosures of FIGS. 11 and 7.

Considering now the disclosures of FIGS. 11 and 7 in comparison, thereglet section 210 remains substantially the same as the reglet section110` except for the fact that a longitudinal series of closely spacedparallel cuts or slots 60 is provided in the section 210, these cuts orslots extending completely through the tear strip 218 and partiallythrough the side walls 214. The cuts 60 are made in such a manner as toentail a definite removal of the material from which the reglet section210 is formed so as to define slots of definite width, as, for

example, by the use of a wide cutting blade. The various cuts 60 -thusestablish clearance regions so that the reglet section 210 as a wholemay be bent to curved form as shown in FIG. 12. The cuts 60 may be madein any desired longitudinal region along the section, but it ispreferable that the end regions of the section 210 remain uncut andstraight so that the medial region only of the reglet section may bedeformed. In FIG. 12, a fragment of a suitable window sash form 232 isdisclosed and to which the reglet section 210 may be nailed in a mannersimilar to that employed in nailing the reglet sections 10 and 12 to theform boards 34, 36, 38 and 40 as show in FIG. 2.

The invention is not Ito be limited to the exact arrangement of partsshown in the accompanying drawings or described in this specification asvarious changes in the details of construction may be resorted towithout departing from the spirit of the invention. For example,although the various reglet sections 10, 12, and 210 have been describedas being formed by an extrusion process from plastic material such aspolyvinyl chloride, it is within the purview of the present invention toform the reglet sections from a suitable soft metal capable of extrusionto produce the desired shapes of reglet sections. Furthermore, althoughno specific illustration has been made herein of a reglet section havingthe cross-sectional shape of the straight reglet section 10 of FIGS. 1and 2 and capable ofbeing bent to curved form to accommodate a roundwindow opening corner, it is obvious that by providing a series of cutsin the reglet section 10 such as the cuts 60 shown in FIG. 11 inconnection with the reglet section 210, the advantageous features ofIthis latter reglet section may be obtained in connection with thereglet section 10.
